When I first installed Subscribe2 everything worked well for several months. I believe it was after the 8.6 update, the daily digest began sending the last 5 newest posts, everyday regardless of whether or not they were new posts. I tried deleting the 5 most recent posts and it continues to send 5 of the next newest posts.
I have the current version, 8.8 installed in the current version of WordPress.
Not sure what could be causing this. Any input would be greatly appreciated.
